Lessons

The Necessary Existent

Ibn Sina’s elegant proof that, beneath all the contingent things that might not have existed, there must be one Necessary Existent that cannot not exist.

Essence and Existence

Ibn Sina’s deceptively simple distinction - between what a thing is and that it is - which reshaped a thousand years of metaphysics.

The Flying Man

Ibn Sina’s dazzling thought experiment - a man created in mid-air, in total sensory blankness, who would still be certain of his own self - six centuries before Descartes.

The Soul and the Active Intellect

Ibn Sina’s theory of how the human mind comes to know - by receiving the forms of things from a cosmic ‘Active Intellect,’ the last of the heavenly minds.

How the Many Flow From the One

Ibn Sina’s grand cosmology - the entire universe emanating, by necessity, from the absolute unity of God through a cascade of intellects, and the storm it provoked.
